I don't know whether or not ricrat read through the whole thread that I referenced. My conclusion, and the conclusion of many others, was that a 52x drive is perfectly safe when used with proper care. The only potential problem would be if you put a damaged disc in the drive. Of course, the same applies to a 48x and even a 40x drive. But, ricrat may have read the various arguments and decided for himself that he would be more comfortable drawing the line at 48x. There is nothing wrong with that.
